Default printable model of a Knucklehead engine

Hiya guys,
I am a machine design engineer by day and a 3d modeler by night.
Rode Harleys half my life and now I own a heavily modified 2000 twin cam as a daily ride.
I have just finished my 3d model of a Knucklehead engine in about 60% scale. The model is to be 3d printed on your FDM printer and then together with the bearings and hardware from Amazon, you build your own model.
I am uploading parts as I finalise the files, which is a lot of meticulous work so bear with me for that process. But photos of my own finished printed model are on printables.
You can find the free to download model here: https://www.printables.com/model/122...klehead-engine
currently working on a Flathead 45 and started collecting drawings and photos of a 59 Panhead as well.
If you work on this model and you find missing files or errors or some other comment, please feel free to add a comment on printables. I will help anybody who tries to build this model.

Excellent work. Vintage HD's motors are cool.
